All modules are produced according to ISO9001 and ISO14001.
EPAD2/CPAD2 Series Common Information
Calibration information
All DEWETRON modules are calibrated at 25°C after a warmup
time of 30 minutes and meet their specications when leaving the
factory. The time interval for recalibration depends on environmen-
tal conditions. Typically, the calibration should be checked once a year.
Calibration certicates are available from DEWETRON as an option. DEWETRON offers several types:
NIST traceable DEWETRON calibration certicate (USA CAL LAB only)
ISO traceable DEWETRON certicate (European CAL LAB only)
Calibration certicate according to ÖKD (equivalent to DKD)
EPAD2 RS-232/485 interface
EPAD2 series modules are controlled via RS-485 interface, and they require this interface for all data
transfers The DEWE-3210 and DEWE-3211 include an internal RS-232/485 converter and interface. This
converter allows communication with all Dewetron signal conditioning modules. To communicate with the
modules, the RS-232 interface must be set to the following parameters:
baud rate: 9600
data bits: 8
parity: no parity
stop bits: 1
handshake: not required
CPAD2 CAN BUS interface
CPAD2 series modules are controlled via the industry standard CAN BUS over CAN 2.0b protocol, and they
require this interface for all data transfers. CAN BUS is an option for both the DEWE-3210 and DEWE-3211
instruments, and must be installed at the factory in order for this interface to be available for CPAD2 connec-
tion.
